To allwhom it ma concern.'

Be it known t at I, CHARLES K. FINE- BEINEE, a citizen of the United States, residing at Laurens, in the county of Laurens and btate of South Carolina, have invented certain new and useful Improvements in Processes for Making Glass Bottles and Similar Articles, (Case Ag) and I do hereby declaro the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertain to make and use the same.

M" invention relates to the manufacture of glass bottles and similar objects, and has for its object to produce a single piece integral bottle or analogous receptacle having distinctive portions, such, for instance, as the neck and body portions, of different kinds of glass such as tinted, glass and plain glass, or glass of different tints, in order to ornament the bottle or other receptacle, or to render the same distinctive for various purposes; thus producing in the glass itself that party-colored eliect now sometimes secured bv applying tinfoil caps and similar sealing devices for such purpose.

The neck or body portion of the glass may be made in several portions, or with several process may also be extended to other objects than bottles and similar receptacles;

Thr-:invention consists in the method of accomplishing*- the results just mentioned in the following manner:

I charge into a parison or preliminary mold masses of diiferent kinds or `colors of glass in a semi-fused or .plastic condition, and of' such a nature as to provide in the 'completed article glass of different or contrasting color or quality; sind while these masses of glass are still plastic and hot, I

unitethemrby forcing into them a plunger in such a manner'and under such conditions that said masses oi' gloss are pressed into intimate contact with ouch other, and become fused or welded togctlnfr permanently and completely at the plane of contact or juneture. 1`

I'find it dcsirablevto keep thev two kinds of` glassscparatcd until, at 'the instant of bringingthcm togethferypressurc maybe applied tripel-feet the weld. This pressure may be applied by theuse of a molding plunger, the :lisplicoment of which plunger should` be `portion of the a and slightly greater or at least equal to the void or space unfilled with glass in the parison mold; it being desirable that the action of the plunger should transmit pressure to the entire mass of fused glass contained iii the mold, and thus insure4 a complete welding action. y

The unfinished article thus formed is sometimes called a parison. It is reioved from the primar mold, its condition being that of practica homogeneity in so far as the union of the two masses of glass is concerned, and is subjected to `fiauther treatment in a blowingmold to form the Icompleted articler One form of a paratus to accomplish the result stated is shown in the accompanying drawings, in which Figure 1 is a vertical sectional view of a paratus, the arranged for mol ing the neck o the bottle;

Fig. 2 is a similar view,

Fig. 3 is a horizontal sectional view on the line 3 3 of Fig'. 1;

Fig. 4 is a vertical sectional view showing the blank arranged within the blow mold;

Fi .5 is an elevation of a completed bottle. Li e reference symbols designate corresponding ,parts in all the views. v

l designates ablank mold of any desired construction, bolted or otherwise secured upon a table 2, and preferably provided with a downwardly tapered cylindrical interior mold cavity 3, to enable the completed blankY 4to be readily lifted out of the blank mold by a nook mold5., in order to transfer the said blank 4 from the blank mold to a blow mold 6. The neck mold5, which is com-y posed oftwo hinged sections connected at the back bv a. suitable'hinge 8 and provided arts beingV the parts being arranged for completing the blank;

with handles 9 at'the front, maybe of any desired construction and interior coniguration to mold a neck ofthe ldesired form.

The neck mold, which is adapted to be arranged against the mouth of the blank mold',

or the blow mold, is' preferably provided in` its lower face with a dove-tailed groove or way 10 formed in the sectionsyofthe collarv or mold, and having inclinedside walls adapted to receivel the beveledsldo .edges 11 l of :1r gate 13. adapted ,tolcloseg for confining therein `a quanti 'lille neck nold 'yof glass 13 mold and adapted to be brought into position tovcause the opening 16 to register therewith after the completion ofthe neck molding operation. The gate 12 is preferably constructed of two longitudinal sections having meetingliiiner ed es 17, connected at the back by a hinge. 18 W ich is adapted to form a sto for engaging the blank mold, to limit the orward or outward movement of the gate 12 with the opening 16 in register with the mouth or entrance of the blank mold.

The glass 14,'r which forms the lower or 'body portion of the bottle, is placed in the mold prior to the placing of the neck mold upon the blank mold 1. After the glass 14 is placed in the blank mold, the neck mold is placed thereon with theimperforate portion of the ,gate 12 covering the mouth or entrance of the blank mold for confining the glass 13 pin the negk or collar mold. The glass 13 is then placed in the neck mold, and the. plun er 19 is mioved downwardly to the position illustrateddnlFig. 1 of the drawings to mold the neck or ring portion of the bottle. The gatel12 is then pulled outward to bring the opening 16 over the mouth or entrance of the blank moldand the plunger is" then moved, downwardly to the limit of its ,downward movement 4to complete the molding of the bottle blank, and the fusion together or welding of the different masses of glass. The plunger forces the glass 14 upward and -causes the same to unite with the glass 13, which forms the neck or ring portion of the bottle.

It will be noted that the {ll-essere of the plunger upon, and into the hot and a'liiio'st liquid glass in the blank mold insures a sti-ong weld and com plete union between the two masses of glassf The strength and finish of the joint here produced isfurther improved by the subsequent operation of blowing,` und also by the final operation of anneal- `6 is of the usual construction, being composed of two hinged sectionsl which are ada ted to be opened to permit the removal of t e bottle, which, after removal, is treated in the usual manner in a leer or annealing oven. adapted to be opened simultaneously with the sections of the neck mold; and the handles 9 are provided with pivoted arms 21 secured by a pivot 22 in a recess 23 in the lower side of each of the handles 9. These pivoted arms are adapted to drop by gravity into notches or openings 24 formed in the sections of the gate 12, as clearly illustrated in Fig. 2 of the drawings. The pivoted arms 21 are normally held within the recesses 23 by pivoted catches or buttons 23l located at the lower faces of the handles. The pivoted arms 21 are adapted to lock the sections of the gate 12 with the handles of the sections of the neck mold so that when the latter is opened, the sections of the gate 12 will also be opened for removal from the neck of the bottle or other rece taicle.

The completed bottle 25, illustrated in Fig. 5 of the drawing, is shown with its neck portion 26 of red glass and its bottoni portion 27 of blue glass for convenience of illustration. Any other distinguishing kind if glass may be employed, as, for instance, the body portion of the bottle may be of ordinary flint glass, and the neck portion of tinted glass. Also while the slidable gate is shown applied to the neck mold at the bottom thereof for making the neck vportion of the bottle distinctive from the rest of the same, the gate may be located at any other desired point so as to Vmake the neck portion of greater or less 1 th.

The gate ma for instance, be tted into the top of the ody mold, in which instance 1t need not bejpivoted, since the opening therein being of the same dimensions es the openin in the body mold, the blank may be casi y withdrawn through it.

It will be seen that the blank may be formed by molding the same in either en upright or inverted position, and that verious other forms of apparatus me be used to carry out the herein descri process. Thus the different kinds of glass may be placed in suitable receptacles and then sua p unger without the interposing o ing gate. Moreover there ma .be several la ers of glass of dierent qualit'es, instead o two only as shown. Furthermore, the colored layers ma run longitudinally of the bottle, or in ot er directions vthan transversely as shown.
